If the bolt can rotate with the control surface, it has to be secured with a castle nut and cotter pin. When the bolt clamps the hinge together onto a bearing, the bolt does not rotate with the control surface movement. Most certificated airplanes use ball bearing equipped hinges; hence, lock nuts are appropriate.
